Title: Coating-density analytic system and method by using image processing
Inventor: EICHI GIYAREN PAAKAA
IPC: G01N21/93
Filed: 1993-05-27
Abstract: PURPOSE: To extract and characterize a low level, narrow and continuous defect by an arrangement, wherein a moving web is illuminated uniformly and an integrating means generates an image data by collecting and integrating density data on the web. CONSTITUTION: A light emitted from a light source (W, halogen light source) 12 is subjected to intensity control through a filter assembly 20, for regulating the illumination intensity before impinging on a light condenser sphere 30. The sphere 30 irradiates a moving coated web 14 with a uniformly diffused light from an output section 32. A two-dimensional CCD camera 34 picks up the image of the web material 14, illuminated with transmitting light. The camera 34 has integrating capability and a high S/N ratio and can operate the system at a low illumination level. An integrated output from the camera 34 is led to a logarithmic amplifier 38 and subjected to offset processing and amplification before being transmitted to a mechanical visual processor 24 where operations are performed according to an image processing algorithm for extracting the defect information.

Abstract: PURPOSE:To decrease the reading errors of data due to external noise, etc. by using plural data holding circuits and comparators to confirm the identity of input data when the external input data is read. CONSTITUTION:When the external data has a change owing to external noise, etc., the difference is produced between the contents of the 1st data holding circuit 303 and those of the 2nd and 3rd data holding circuits 304 and 305. Thus a data comparator 306 delivers an L level to a data input controller 301 in the form of an error detection signal. The controller 301 resets a program counter 307 by an amount equivalent to a data input instruction and at the same time reads again the data same as preceding one through a memory read signal line 351 and an I/O read signal line 352. When it is impossible to confirm the identity of data even after plural times of trial, the occurrence of an error is informed to both inside and outside devices from the controller 301 through an output line 366. Then the operation is discontinued.
